On July 8, Yoha Solar completed the shipment of its self-developed YH-EL3005 top-capturing automatic post-lamination EL tester. The customized equipment will be delivered to an overseas customer and deployed on a semi-automatic PV module production line. Tailored to the client’s actual production conditions, the optimized design perfectly adapts to local workshop environments and line operating parameters while maintaining superior inspection performance. This delivery marks another solid step in Yoha Solar’s global expansion and further demonstrates the company’s strong customized service capabilities for overseas projects.
Different from standard off-the-shelf models, the YH-EL3005 is a fully customized solution developed specifically according to the customer’s line characteristics. During project implementation, Yoha Solar’s technical team conducted in-depth communication regarding production workflows, on-site layout and inspection requirements. Targeting the transmission mode, installation space and localized maintenance demands of overseas semi-automatic production lines, the team optimized the overall equipment dimensions, transmission logic and electric control interaction. While retaining core high-precision testing performance, the equipment is fully adapted to local power supply and pneumatic conditions, enabling seamless integration with the customer’s existing production line and meeting strict requirements for post-lamination inspection efficiency and defect accuracy.
Powered by in-house developed electroluminescence testing technology, the YH-EL3005 supports comprehensive inspection of monocrystalline and polycrystalline PV modules with an ultra-large effective testing area of 3048×509mm, applicable for both pre-lamination and post-lamination quality control. Equipped with a customized 24-megapixel industrial camera and adopting area-array downward direct capturing mode, the device delivers distortion-free and corner-accurate imaging with controllable resolution. It precisely identifies microcracks smaller than 0.03mm, as well as cell fragments, hidden cracks, broken grids, cold solder joints and mismatched electrodes, providing reliable quality assurance for PV module production.
In terms of line compatibility, the equipment adopts a mature domestic industrial control architecture to facilitate convenient local maintenance. It features a longitudinal transmission design with short-edge feeding and fully automatic loading and unloading. The single-module testing cycle is less than 20 seconds with adjustable operating speed, and the image acquisition time ranges from 100ms to 700ms, flexibly adapting to diverse production takt times. Integrated with automatic barcode archiving and visualized operation interface, the system supports magnified image viewing and automatic data storage, satisfying digital quality traceability requirements for overseas factories.
Yoha Solar has long specialized in the R&D and manufacturing of PV testing equipment, consistently delivering application-oriented customized solutions. Supported by independent integrated software and hardware technologies, the company flexibly optimizes transmission structures, electric control programs, testing algorithms and equipment appearances for fully automatic, semi-automatic and renovated legacy production lines worldwide.
